Q: What are the core structural advantages of unit-type flexo presses compared with stack-type and CI-type models?
A: The unit-type design features horizontally independent color stations with a longer web path. Each unit is equipped with an individual drying system, effectively preventing dot gain and ink set-off during high-speed operation. It delivers superior registration stability, ideal for long-run production and high-quality flexible packaging printing.
Q: What designs enable stable high-precision registration even at maximum running speed?
A: The machine adopts a full servo shaftless drive system. Each color unit is driven by an independent servo motor, combined with automatic pre-registration and closed-loop real-time correction. The registration accuracy is steadily maintained at ±0.10 mm without deviation at high speed.
Q: How does the unit-type flexo press improve job change efficiency for diversified and small-batch orders?
A: It is fitted with quick plate changing, quick anilox roller replacement, automatic on-off impression and job recipe storage functions. The job change time is reduced by over 50% compared with conventional machines, greatly boosting productivity for multi-batch production.
Q: What drying system is adopted? How to ensure fast ink drying and avoid ink set-off at high speed?
A: Each color station is equipped with an independent hot air drying system with adjustable air volume, temperature and wind speed. It enables instant drying for water-based and UV inks, and prevents ink sticking to plates and substrates at the running speed of 250–350 m/min.
Q: Does the machine support one-stop inline processing? What functions can be integrated?
A: Yes. It supports full inline production, integrating printing, drying, lamination, slitting, die-cutting, rewinding and defect detection. All units work synchronously to finish products in one pass, raising efficiency and cutting labor costs.
